    苯酚-1-酮光敏剂中阳离子取代基对抗菌剂光动力功效的影响。
    摘要:
    阳离子光敏剂(PS)的光介导的病原体杀灭是一种有前途的抗菌方法,可避免使用抗生素时出现的耐药性。在这项研究中,我们重点研究了苯丙氨酸-1-酮PS中取代基的影响。研究了针对包括革兰氏阳性和革兰氏阴性病原体在内的带正电荷的部分(包括伯脂肪族,季脂肪族,芳族铵和胍鎓阳离子)的光动力功效。考虑到这些官能团的空间需求和亲脂性改变,我们推导了结构-活性关系。SAGUA是该系列中最有效的PS,在蓝光(20 mW cm(-2))照射60 s后,以10μM的浓度杀死细菌的最大功效达到≥6log10步杀死细菌(1。2 J cm(-2))而没有表现出固有的暗毒性。它的胍基部分除能吸引离子电荷外,还能够与细菌表面的羧基形成强力的双齿和定向氢键。这可以补充快速有效的抗菌活性。

  • Improving Photodynamic Inactivation of Bacteria in Dentistry: Highly Effective and Fast Killing of Oral Key Pathogens with Novel Tooth-Colored Type-II Photosensitizers

    Increasing antibiotic resistances in microorganisms create serious problems in public health. This demands alternative approaches for killing pathogens to supplement standard treatment methods. Photodynamic inactivation of bacteria (PIB) uses light activated photosensitizers (PS) to generate reactive oxygen species immediately upon illumination, inducing lethal phototoxicity. Positively charged phenalen-1-one derivatives are a new generation of PS for light-mediated killing of pathogens with outstanding singlet oxygen quantum yield ΦΔ of >97%. Upon irradiation with a standard photopolymerizer light (bluephase C8, 1260 ± 50 mW/cm(2)) the PS showed high activity against the oral key pathogens Enterococcus faecalis, Actinomyces naeslundii, Streptococcus mutans, and Aggregatibacter actinomycetemcomitans. At a concentration of 10 μM, a maximum efficacy of more than 6 log10 steps (≥ 99.9999%) of bacteria killing is reached in less than 1 min (light dose 50 J/cm(2)) after one single treatment. The pyridinium substituent as positively charged moiety is especially advantageous for antimicrobial action.
